It is difficult to differentiate papillomas macroscopically from inflammatory nasal polyps, therefore we must examine microscopically, because of the differences of the treatment and the prognosis. Papillomas are classified into two types according to the epithelial growth. The one is an exophytic type which proliferates outward from the surface, and the other is an inverting type which invades the underlying stroma. The latter tends more to be malignant than the former. In our case, the tumor arising from ethmoidal sinus occupied nasal cavity and was completely removed by caldwell-Luc's operation. The tumor is now free from recurrence with an exploratory immune-therapy for six months after the operation., 論文}, pages = {426--429}, title = {[原著]副鼻腔乳頭腫 (Epithelial Papilloma) の一例}, volume = {2} }
